AI Technical Summary
In existing tractor hydraulic steering systems, leaks are prone to occur at the connection between the oil tank end cap and the hydraulic oil tank body. The lack of a filter allows impurities to enter, and the welded joints of the oil pipes are prone to cracking, affecting the stability and safety of the system.
The hydraulic oil tank structure has been improved by adopting a blind hole design for connecting flange welding, adding an air filter, a split oil tank design with reinforcing ribs, an internal oil filter and positioning sleeve, and using a spring to fix the oil filter.
It reduces hydraulic oil consumption, prevents impurities from entering, enhances system stability and shock resistance, and lowers maintenance costs and safety hazards.

TECHNICAL FIELD
[0001] The utility model relates to agricultural machinery technical field especially relates to an improved tractor steering oil tank structure. BACKGROUND
[0002] The mechanization and intelligent development of modern agriculture put forward higher and higher requirements to the hydraulic system. Figure 2 And Figure 3 For the hydraulic oil tank structure of an existing tractor, the oil tank end cover is connected to the hydraulic oil tank body through bolts, and there are oil pipes at the bottom of the hydraulic oil tank body, which are connected to the gear pump and the steering gear respectively, and together with other components and auxiliary parts, the hydraulic oil tank structure constitutes a complete hydraulic steering system.
[0003] 1. The installation flange threads between the oil tank end cover and the hydraulic oil tank body are through, and if the glue is not good or the oil temperature rises and the pressure increases during use, oil may spurt out of the bolt holes, causing oil loss and the risk of fire when the oil spatters on the engine body.
[0004] 2. The hydraulic oil tank end cover does not have a filter installed, but only has a cover with a sealing ring and an oil absorption sponge, which cannot play the role of oil filtering, and impurities in the oil and air can easily mix into the steering system, causing wear of hydraulic components or abnormal operation of the system.
[0005] 3. The entire hydraulic oil tank is fixed on the engine, and the oil tank bottom oil suction iron pipe is welded on the hydraulic oil tank body.
[0006] Therefore, it is necessary to develop a reasonable tractor steering oil tank structure. UTILITY MODEL CONTENTS
[0007] The utility model aims at providing an improved tractor steering oil tank structure to overcome the above problems or at least partially solve the above problems.
[0008] To achieve the above purpose, the technical scheme of the utility model is as follows:
[0009] This utility model provides an improved steering oil tank structure for tractors, including a hydraulic oil tank body and an oil tank end cover. A connecting flange is welded and fixed to the upper side of the hydraulic oil tank body, and an oil tank end cover is provided on the upper side of the hydraulic oil tank body. Connecting bolts are connected to the oil tank end cover, and connecting bolts are connected to the connecting flange. An air filter is connected to the lower side of the oil tank end cover and is located inside the hydraulic oil tank body. An oil suction pipe and an oil return pipe are respectively connected to the lower side of the hydraulic oil tank body, and a reinforcing rib is also welded and fixed to the lower side of the hydraulic oil tank body. The other end of the reinforcing rib is welded and fixed to the oil suction pipe and the oil return pipe respectively. An oil filter is also provided inside the hydraulic oil tank body. The oil filter is located on one side of the oil suction pipe and is connected to the upper end of the oil suction pipe.
[0010] As a further embodiment of this utility model, the hydraulic oil tank body is divided into upper and lower parts, and the upper and lower parts are fixed together by welding.
[0011] As a further embodiment of this utility model, a positioning groove is provided at the top of the interior of the hydraulic oil tank body, a positioning sleeve is provided on the lower side of the positioning groove, and a positioning protrusion is integrally connected to the upper end of the positioning sleeve, and the positioning protrusion matches the positioning groove. The positioning sleeve is fitted onto the oil filter.
[0012] As a further embodiment of this invention, a spring is also provided inside the positioning sleeve, and the spring is positioned between the positioning sleeve and the oil filter.
[0013] This utility model provides an improved structure for a tractor steering oil tank, with the following advantages:
[0014] 1. By directly welding the connecting flange to the hydraulic oil tank body, the threaded hole on the connecting flange can be changed from a through hole to a blind hole. Because the inner side of the connecting flange cannot be welded to the oil tank body, when the hydraulic system works for a long time and the hydraulic oil temperature rises, oil vapor will spray out from the gap. After changing to a blind hole, the oil vapor cannot pass through here, which greatly reduces the loss of hydraulic oil.
[0015] 2. The oil tank end cover is equipped with an air filter, which can prevent impurities in the air or oil from entering the entire hydraulic system during refueling, ensuring the stability and smoothness of system operation and reducing maintenance costs.
[0016] 3. When welding the suction and return oil pipes to the main body of the oil tank, reinforcing ribs are added to reduce the vibration of the engine when it is transmitted to the hydraulic oil tank, making it more stable and reliable, reducing the occurrence of cracks at the weld, improving work efficiency, and reducing warranty costs.
[0017] 4. Compared with the previous version, it is more aesthetically pleasing and reliable, bringing certain convenience to product sales. Attached Figure Description
